Hi Philly!
Afraid not!
System Restore specifically does not touch files that you create.
Jan Karel Pieterse's AutoSafe might be an Addin that will be better at
preventing this problem.

Here's the blurb:
The standard Autosave (note the spelling) utility that ships with
Excel just saves workbooks at a set interval, overwriting the file on
disk. This is not very convenient if you planned to leave the master
file intact and save the changed workbook using a different filename.
It also does nothing to simplify recovery of unsaved/changed documents
after a system crash. This Autosafe utility creates copies of open
workbooks at regular intervals in a separate (user-selectable)
directory. It does not overwrite the master file(s), that is up to the
user to do, using normal methods. As soon as a workbook is closed the
backup copy is deleted from the backup directory. If an abnormal
termination of Excel occurs, the backup copies remain on disk, and
Autosafe finds them the next time Excel is started and presents
recovery options to the user. This utility is freeware only for
individual (private) users.

Can i retrieve data entered into a spreadsheet (after several hours
of work) when I accidentally clicked "no" when asked if I wanted to
save changes. I attempted to system restore, however, that failed to
return my previous entries.
